Title: Digital recording and playback device
Inventor: TAKI HIDEO
IPC: G11B5/09
Filed: 1979-10-02
Abstract: PURPOSE: To make easy the circuit constitution and its circuit control required for data processing, by recording another digital signal on another track, based on a clock signal picked up from a digital data on a recorded track.  
     CONSTITUTION: A reference clock generating circuit 3 outputs a clock signal S 1  of predetermined frequency to a clock switching circuit 4. In this switching circuit 4, based on the reference signal in a playback data detection circuit 5, a clock signal is fed to a recording circuit 2. On the other hand, at the playback data detection circuit 5, for example, by detecting the frame synchronizing signal in playback data, whether or not the data is reproduced is discriminated, and if no data is reproduced in the switching circuit 4, the 1st clock signal S 1  is fed to the recording circuit 2 and if reproduced, the 2nd clock signal S 2  is fed to the circuit 2. Thus, the circuit constitution and the circuit control required for playback data processing can remarkably be simplified.

Title: Acoustic echo canceller
Inventor: NAKAGAWA TETSUYA
IPC: H04R3/02
Filed: 1995-05-26
Abstract: PURPOSE: To realize the echo cancellation with one DSP or microprocessor by reducing the processing capacity in the echo canceller for a long echo. CONSTITUTION: Coefficient of coefficient decision sections 1308 to 1310 of a low frequency band acoustic echo canceller 1312 is updated for an even number time and coefficient of coefficient decision sections 1320 to 1322 of a high frequency acoustic echo canceller 1324 is updated for an odd number time. That is, the update of the filter coefficient for a band split type acoustic echo canceller is conducted alternately between bands to interleave the filter coefficient update processing amount. Thus, the processing capacity is much reduced to allow only one conventional DSP to realize the cencellation of a length of echo required practically and the interleaving of coefficient update is controlled to trade off between the processing capacity reduction and the convergence characteristic.

Title: Vapor growth method of iii-v group compound semiconductor
Inventor: OOISHI MAMORU
IPC: H01L21/205
Filed: 1983-07-15
Abstract: PURPOSE:To capture the oxygen remaining in the growth region and obtain high quality growth layer by adding an organic metal compound including Al, in the constant concentration, into the raw material gas during vapor growth of the III-V group compound semiconductor. CONSTITUTION:In case an organic metal compound including Al is supplied with other raw material compounds to the growth region in the vapor growth of the III-V group compound semiconductor, the chemically active Al is separated by a thermal decomposition. The separated Al atom combines with oxygen in a mixed gas consisting of the raw material gas an carrier gas and thereby an Al oxide is produced. Moreover, since the Al oxide has comparatively small specific gravity, it is exhausted from the exhaust port of growth apparatus in accordance with the flow carrier gas, not resulting in adverse effect on the growth layer. As the organic metal compound including Al, trimethyl aluminum, triethyl aluminum or triisobuthyl aluminum are used.

Title: Original plate for shadow mask and its production
Inventor: OKITA TOMOYOSHI
IPC: C22C38/08
Filed: 1986-06-04
Abstract: PURPOSE:To improve the heat economy in annealing and the annealing before pressing in the production stage of an original plate and to eliminate the need for warm pressing by limiting the contents of C and O of the original plate consisting of an Fe-Ni alloy. CONSTITUTION:The low thermal expansion alloy which consists essentially of Fe and Ni and is formulated to contain <=0.008wt% C and <=0.0060% O is used as stock. Such stock is subjected to recrystallization annealing as cold rolled or after the cold rolling, then to temper rolling within about 2-5% at need. The C in the stock is an element which is undesirable in terms of softening. The strength decreases with a decrease in the content of C. The strength is approximately constant at <=0.008%; therefore, said content is determined as an upper limit. The content of O in the stock significantly affects the grain growth at a relatively high temp. of >=950 deg.C in particular and the austenite grain size grows more largely as the content of O is lower. The decrease of the annealing temp. in the respective stages of the production process is thus permitted by the above-mentioned method.

Filed: 1987-05-27
Abstract: PURPOSE:To uniformize a film forming distribution and to extend the life of a target by disposing plural magnetic pole bodies along the direction intersecting with the moving direction of the target and executing sputtering over the entire area of the target. CONSTITUTION:The target 12 is mounted on a 2nd electrode 7 and a wafer 5 is set to a 1st electrode 6. A DC voltage is impressed between the two electrodes 6 and 7 and the target 15 is rotated by a motor 13. Plasma 18 formed on the main face side of the target 12 is restrained by magnetic fluxes 17 formed by the respective target bodies 16 and is confined near the target 12. Since the target bodies rotate integrally with the plate 15, the local plasma region revolves around the center of the target 12. As a result, the pitch arrangement between the S and N poles of the plural target bodies 16 are different and, therefore, the plasma 18 passes uniformly over the entire area on the main surface of the target 12 so that the plasma treatment uniform over the entire area of the main plane of the target 12 is executed.

Title: Frame synchronization protection circuit
Inventor: OYAMA TAKEKATSU
IPC: H04L7/08
Filed: 1991-04-30
Abstract: PURPOSE:To lock the circuit to new synchronization after input data changeover by discriminating the presence of the detection of coincidence/noncoincidence of synchronization for a period when an output signal of a frame counter is counted. CONSTITUTION:A coincidence pulse K1 of frame synchronization by a complete pattern synchronization detector 1 and a noncoincidence pulse K2 of frame synchronization by a correlation pattern synchronization detector 2 are detected by a detection presence discriminator 14 for each output period of a discrimination period signal C3 outputted from a constant counter 13. When the pulses K1, K2 are not entirely in existence, it is discriminated as a fault of synchronization, a fault detection pulse sets a flip-flop 9 via an OR gate 15 and a detection pulse Pd from the detector 1 resets a frame counter 6 via an AND gate 11. Thus, the circuit is locked to new synchronization after input data changeover.
